Here's an interesting article by Christopher Peterson looking at some of the relationships between Batman and his supporting cast.

Huntress, Robin, Robin, Robin, Robin, Robin, Katana, The Outsiders,
Lucius Fox, Squire, Batgirl, Batgirl, Batgirl, Batwing, Vicki Vale,
Spoiler and more zany characters than subdivisions of Wayne-Tech serve
as surrogate relationships to fill the hole created in Crime Alley.
These bonds serve a variety of functions in Batman’s life; from
comrades, pawns, lovers, friends and wards but is anyone of them truly
necessary?

The Dark Knight claims no one can understand his struggle, but is it
possible that someone amongst his rotating sidekicks is more important
to him than The Mission he dedicated his entire life towards?

An expert panel discusses the various Batmen of yesteryear and the validity of their varying interpretations.

"We're here to explore not the mainstream
Batman, but the other iterations of Batman that have occurred throughout
the media," said Ferranti. "A gentleman by the name of Bat-Mite
actually put it best on an episode of 'The Brave and the Bold,' so let's start with a clip."

With that, Miereanu played a clip from the episode "Legends of the
Dark Mite," in which the fifth dimensional imp addresses the concept of
"Not my Batman," to a parody of a convention audience.

"Batman's rich history allows him to be interpreted in a multitude of
ways," said Bat-Mite. "To be sure, this is a lighter incarnation, but
it's certainly no less valid and true to the character's roots as the
tortured avenger crying out for mommy and daddy."

"That was so meta I actually turned inside out," said Patterson following the clip.

"Essentially we're here to make the case that there's room for more
than one kind of Batman," said Ferranti. "To celebrate these other sides
of Batman as a character but also to note that each one of us, at some
crucial point in childhood met, 'The Batman,' but also met, 'A Batman.'"

In honor of the seventy-fifth anniversary of Batman, we’re doing four
straight months of polls having to do with Batman, culminating with the
official 75th anniversary of Batman on July 23rd. We’ve done Batman
covers, Batman characters, Batman creastors and now, finally, Batman
stories!
You all voted, now here are the results of what you chose as the 75 Greatest Batman Stories!

Most
folk’ll tell you the use of pop culture iconography in ritual began in
the 80′s with Chaos Magick and the IOT. A few folk’ll tell you it
started earlier with people like William S. Burroughs, who was known to
use a cardboard stand-up of Mick Jagger for “rites of performance.” But I
think it can be traced back to the beginning if you consider that at
one time, even the Sumerian gods were pop sensations.

Those in the chaos current have always accepted the use of pop
culture as being magically relevant. Just examine the successful
integration of the Cthulhu Mythos by Anton LaVey, Phil Hine, and many
others into the magical landscape over the last fifty years. Borrowing
from any archetypal pool is considered okay, as long as it gets results.
Devotion to an entity isn’t necessary for it to be useful as a magical
tool.

Recently, though, a trend has popped up that I’ve found myself right
in the middle of: serious religious devotion given to fictional
characters drawn from pop culture. I’m a member of the Sons of the Batman,
a magical group that honors the Caped Crusader. Although it may appear
to be a joke or an intellectual exercise, it’s definitely not, and we
take the worship of Batman very seriously.
And we are by no means the only ones.

Probably the most successful religious group inspired by a fictional source (outside of Scientology) would have to be the Church of Jediism.
The Jedis have even gained tax-exemption in the US as a recognized
non-profit religious organization. Their religion draws from the
fictional universe of Star Wars, but they do not recognize its stories
as any sort of scriptural reference. Instead, they see it as a point of
philosophical inspiration, from which they’ve drawn the “16 teachings” and “21 Maxims.” They definitely believe in the Force, though.

Jediism gained attention during the 2001 New Zealand census, after an e-mail campaign inspired more than 53,000 to list “Jedi” as their religion. In the England and Wales census
that year, over 390,000 claimed the same. The figure dropped to 176,000
last year, still outnumbering all the other “alternative” religions
(including Atheism, numbering 29,000).

In 2004, Matrixism announced its arrival. It considered the Matrix
films and related media to be a “sacred text,” which are said to be
inspired metaphors of an idea articulated by `Abdu’l-Bahá’, son of Bahá’u’lláh, founder of the Bahá’í faith. According to its website, there are over two thousand adherents to the “Path of the One.”

There’s also a Church of Elvis, a Church of all Worlds (based on the fictional religion from Robert Heinlein’s Stranger in a Strange Land), and even the first rumblings of a cult dedicated to My Little Pony. I’m sure with more digging, one could find many more examples.

Jediism and Matrixism were studied by Dr. Adam Possamai,
along with other pop-inspired religions that he termed, “hyper-real
spiritualities.” Possamai believes that these groups are the product of
what he calls a “McDonaldised Occult culture,”
in which the beliefs that were once kept secret by groups like the
Golden Dawn or the OTO are now easily found on the internet and
bookshelves everywhere, making open comparison an easy task. Compound
this with a desire to synthesize a consumerist culture with the search
for a spiritual path, and you’ll have some seekers finding a parallel
between the religious teachings of more traditional sources and the
themes found in fiction.

My own entrance to these ranks came about when I had the epiphany
that my own beliefs were influenced not by Christ, Mohammed, Krishna, or
Pan, but by the stories of the Batman. Without knowing it, by immersing
myself within the Batman myth since the age of three, I was allowing it
to mold my thinking as my ego and sense of morality formed. By
acknowledging and actively reinforcing this belief structure, I began to
experience a real clarity in my personal spiritual practices and the
strange sense that I had possibly stumbled onto a kind of magical
lynchpin. After years of experimenting with the deities of a variety of
cultures, the myth that seemed to inspire me the most was the one I had
so happily consumed since childhood, never imagining it to be divine in
any way.

The switch from viewing these pop culture icons as mere tools to use
in the practice of results magic to objects of spiritual devotion seems
to coincide with a general trend. It appears that the prevailing themes
of cynicism and irony which defined the attitude of occultism in the
90′s has been replaced with a hunger for sincerity. Unlike their
predecessors, the modern youth culture is unabashed by its reliance on
consumerism and seems willing to integrate it into their spiritual life.

It’s possible that rather than just being an interesting blip in
religious evolution, devotion to the icons of pop culture may very well
be the next serious movement in magic.
